assumptions from generic code. This implements the minimal set of changes needed in libvirt to launch a PowerPC-KVM based guest. It removes x86-specific assumptions about choice of serial driver backend from generic qemu guest commandline generation code. It also restricts the ACPI capability to be available for an x86 or x86_64 domain. This is not a complete solution -- it still does not guarantee libvirt the capability to flag non-supported options in guest XML. (Eg, an ACPI specification in a PowerPC guest XML will still get processed, even though qemu-system-ppc64 does not support it while qemu-system-x86_64 does.) This drawback exists because libvirt falls back on qemu to query supported features, and qemu '-h' blindly lists all capabilities -- irrespective of whether they are available while emulating a given architecture or not. The long-term solution would be for qemu to list out capabilities based on architecture and platform -- so that libvirt can cleanly make out what devices are supported on an arch (say 'ppc64') and platform (say, 'mac99').
